linux: enable TCP_CONG_ADVANCED

Browse source 
TCP_CONG_ADVANCED is enabled by default on x86_64[1] in the upstream.
Although it is not the case for aarch64[2], many distributions, such as
Debian[3], Fedora[4] and Gentoo[5], choose to enable it in their
distribution kernel.

With this patch, aarch64 users can choose many other TCP congestion
algorithms, which may improve their network performance.
